Application December 21, 1948, Serial No. 66,460

sq fl mfit (Cl. 1Q1-.-=368) Thi invention relates. to. a new and improved: type holding apparatus for use with stamping machin s- Eoil, stamping machines. are. those. machines in which av stamping head. employs-typeiin combination with heat, to cause foil, such as gold foil, to. be imprinted on various. objects according to the type held in the stamping. head. Such a.

stamping head is shown in my copending ap-v plication entitled Foil Feeding Device I For Stamping Machines, and having. Serial: No. 6.6-,459and filed December2l', 19.48;

It is, therefore, a principal. object of this in-v vent cn to provide. a type holding means for-foil stampin machine.

An important object of this invention is the provision of type holding means for foil imprint= ing machines in which the. type is securely held during the. stamping or imprinting operation.

Another, important object of this invention is to supply type holding means'for a foilstamping machine having plural spring'means for resisting lateralas well as vertical movement withrespect to the tamping machine. during theentire opera ion of: the. imprintin p o A; iurther objectjof-thisinvention is to provide a type holding stick. or theJike, having integralprin m ans. in a E-head for. the; purpose of exerting; lateral force. against.- a. cooperative T- slot in the stampinghead, thus maintainingthe trnestiel; in fixedposition with respect tothe tampin h ad Another and further important 'obje ct of this invention is to provide a stamping'head'having a... type. receiving socket and a leaf spring disposedin a. channel extending laterally across the top thereof inwhich the endportions aredisposed within thechannel and the central portion extends downwardly within thesocket, whereupon a type stick inserted in the-socket may easily pass overthe ends of thespringwithin the chan nel and when centered inthesocket-is yieldably held by the downwardlyextending central por-tion of espring.

A further importantobjectoi-this invention is. the provision of astamping-head 'for foil imprinting machines inwhicha type-holding stick' maybe inserted from only one end thereof and the type stickis equipped with meangasseciated therewithto-permit either end thereofto be inserted into the single end of the stamping-head and having cooperative means on the stamping headior engaging means on the -.type stick for centering the type stick withinthe. stamping head;

As shown in the drawings:

The reference'numeral IO- indicates generallyan inverted U-shaped-channel member which is adaptedto form part of astamping head for use The inverted;

on a. foil imprinting machine; channel includes acrosstop member ll-,- downwardly extending side membersl2 and I3, and flanges Mand IS in the form of dovetails, adjacent the top H for easy sliding insertion within the reciprocating'head fixture ofa foil imprinting machine as shown in my co-pending application mentioned above. The inverted U- shaped member forms a laterally. extending channel or socket I6; within whicha'type holder maybe easily'slid; The U-shaped member It) includes T-head slot portions "and l8'adjacent theundersideof the top I I and extending inwardly within the sides l2 and'l3. The. functionof the T-head slot is to receive a T-head on a type holding stick to prevent vertical dis! placement of the type holder when it is. in posi-.

.tion within the u-shaped channel member. [6.

A-narrow, shallow channclor groove [9 ;is provided within the channel it along thetop thereoi-withinthe topside ll andjcentrally between me h s. 2 and la; to hold a leafspring 20." An end'2l of the spring he channel I 9 is adapted is completely disposed within the channel l9 and fastened therein by means of a screw or the like 22. The middle portion of the leaf spring 20 designated by the numeral 23 is bellied or curved downwardly as best shown in Figures 1 and and thereupon the opposite end 24 is turned upwardly and lies within the channel [9 as does the holding end 2|. The downwardly extending central portion 23 of the leaf spring is therefore located in the plane of the T slots I I and i8 and upon sliding passage of the type holder within the inverted U-shaped channel member ID, the spring 29 has its central portion 23 compressed and thus the type holder is firmly held Within the channel [6 by reason of the spring 20 exerting a downward force upon the type holder.

Figure 2 shows the type stick holder adapted to be inserted within the channel In shown in Figure 1. The holder of Figure 2 is substantially L-shaped, having a cross head 25 and a back wall 25. End walls 21 and 28 complete the structure for the type holder. The top 25 of the type holder or type stick as it is commonly called in the industry, is of a thickness equal to the T head slots i1 and [8 in the inverted U-shaped channel Hi. The top 25 has laterally projecting side portions 29 and 30 for cooperative engagement with the slots I! and I8 in the channel H).

The top 25 of the type stick thus constitutes a T head which slides into the T slots in the channel and holds the type stick against relative vertical movement between the type stick and holder It. The top 25 is relatively fiat, and upon insertion of the type stick within the channel I0, the spring 20 is compressed, thus holding the type stick in any position desired.

As best shown in Figures 2 and 8, the laterally extending edge or lip 29 is provided with an integral spring 31 which is formed by slitting the lip 29 at 32 and thereupon forming the central portion of the strip 3| convexly outwardly to constitute a laterally extending spring 3|. Thus when the type holder is inserted into the holding head It it is held in two directions by means of dual springs. The first spring means shown at 20 is adapted to urge the type holder in a downward or vertical direction, and the second spring means is that shown at 3! which urges the type stick transversely within the type stick holder l0, thus insuring that regardless of looseness of fit of the lips 29 and 30 within the cooperative slots i! and [8 the type stick will be firmly held within the holder, thus enabling clear impressions to be made by this imprinting machine.

The underside or bottom of the back wall 26 is calibrated in increments of type spacing as shown at 33. The type, whether it be a name and address or other symbols is placed within the L-shaped holder against the back wall and up against the top 25. When the type is inserted within the holder the holder is turned upside down so that the type maintains its position after placement. When the type row is completed a hand screw 34 is turned up against the end of the type by means of rotating a knurled or otherwise milled handle 35, thus pressing the type against the far end wall 28. As shown in Figures 2, 3 and 8, the hand screw 34 threadedly engages the end wall 21 at 36.

Styles of type vary considerably in size and although one style of type may take up the entire space between the back wall 26 and the depth of the holder as indicated by the Width of the end walls 21 and 28, certain types are of smaller sizes and thus of necessity a lateral spacing member is provided as shown at 31. This spacer member is shown in detail in Figure 9 wherein the member 31 is shown slitted at 38, forming an end finger member 39. This finger constitutes an integral spring for the spacer member 31. When the member 31 is inserted in the type holder as shown in Figure 8, the spring 39 causes an endwise force to be exerted on the end wall 27, whereupon the lateral spacing member is firmly and rigidly held within the type holder. The spacer 3! insures that the hand screw 34 will exert a pressure centrally of a row of small type.

Figure 3 best shows the assembly of the type stick within the holder. In order that the relatively long type stick may be conveniently centered within the type stick holder, the lips 29 and 30 are provided with opposite and diagonally disposed ledges or notched cutoffs as shown at 40 and ll in Figures 2 and 7 respectively. As shown in Figure 6, a stop member 42 is fastened by means of rivets or bolts or the like 43, over the far end of the T slot l8. Thus as the type stick is slid into the holder, the ledge 40 strikes the stop 52, causing an automatic centering of the type stick within the holder. The ledges 4E} and 4| are spaced an equal distance from the end walls 28 and 21 respectively, and thus permit an extension of the type stick beyond the end of the inverted U-shaped channel that amount which it does extend beyond the ledges 40 and 4|. If it is desired to make an impression of the type within the holder in reverse direction, the type stick is then turned around and inserted into the same end of the channel and in that event the ledge 4| strikes the stop 42 and also centers the type stick within the holder head It].

In the operation of this device the inverted U-shaped head t is fastened to a stamping head preferably by means of sliding the dovetail extension members M and I5 into cooperative socket dovetail slots in the stamping head of a stamping machine. Type of the desired size and in desired order is arranged in the type stick and the hand screw 34 tightened against the end of the row of type by means of rotating the handle 35. The type stick is then inverted and the T head 25 inserted into the T slots I! and I8 of the head I 0. The springs 29 and SI hold the type stick in the channel Hi and with sufficient relative rigidity to permit impressions to be made without fear of shifting of the type stick within the stamping head.

It is believed'that herein is provided a type holder for stamping machines which is simple in construction and yet performs all of its required functions. It is further believed that the spring mounted in the depressed channel of the inverted U-shaped channel member performs a very desirable function of maintaining the type stick holder free of relative vertical movement. This taken in combination with the spring 3| which is formed integrally with the T head of the type stick to exert a side pressure forms a very unique type holder for stamping machines,

Numerous details of construction may be varied throughout a wide range without departing from the principles disclosed herein and I therefore do not propose limiting the patent granted hereon otherwise than as necessitated by the appended claims.
